How the Enterprise Management Incentive Scheme Works for UK Startup Option Holders

The Enterprise Management Incentive scheme is a UK government approved option scheme that allows qualifying companies to grant share options to employees on tax advantaged terms. An employee who receives and exercises EMI options, and holds the resulting shares for the required period, pays capital gains tax at the lower entrepreneurs relief rate on any gain rather than income tax at the marginal rate. The difference in tax treatment between an EMI option and a non-approved option can be material at the point of exit.

The Distinction That Matters

EMI options do not automatically qualify for the tax advantage. The company must meet size criteria: gross assets below £30 million at the time of grant, fewer than 250 full-time equivalent employees. The employee must work at least twenty-five hours per week for the company or, if less, at least seventy-five percent of their working time. The option must be granted over ordinary shares. And critically, the exercise price must be agreed with HMRC through a valuation submission before the grant is made, or the tax advantage is at risk.

A company that grants options without completing the HMRC valuation submission, or that grants options after the company has exceeded the gross assets threshold, has created option grants that do not carry the EMI tax advantage. The employees believe they hold EMI options. The grants are not compliant. This discrepancy is discovered at exit, when the tax treatment applied by HMRC differs from what the employees were expecting.

Why It Surfaces in a Raise Process

In a Series A due diligence process, the investor's legal team reviews the option pool documentation to confirm that EMI options have been granted in compliance with the scheme rules. Non-compliant EMI grants are a governance deficiency that must be disclosed to prospective investors and, depending on the materiality, may require retrospective correction or employee notification.

The Common Structural Error

The most common error is granting EMI options without first obtaining an agreed HMRC valuation. The HMRC valuation sets the exercise price at a level HMRC accepts as market value. Options granted without this agreement may be challenged on the basis that the exercise price was not set at market value, which removes the tax advantage and creates an income tax liability for the employee at exercise rather than a capital gains tax liability at disposal.
